Why Has My Amana Furnace Shut Off?
Posted On: November 27, 2023
If your furnace has shut off unexpectedly, there could be several reasons behind it.
Here are some common issues that might cause a furnace to shut off, and it's important to note that for safety reasons, it's recommended to consult a professional HVAC technician to diagnose and address these problems.
Here are some potential reasons for your furnace shutting off:
Thermostat Issues: Incorrect thermostat settings or a malfunctioning thermostat could be causing the furnace to shut off.
Check the thermostat settings to ensure they are configured correctly, and replace the batteries if applicable.
Clogged Air Filters: Dirty or clogged air filters can restrict airflow, causing the furnace to overheat and shut off as a safety measure.
Regularly check and replace the air filters to ensure proper airflow.
Flame Sensor Issues: The flame sensor is a safety device that detects the presence of a flame.
If it's dirty or malfunctioning, the furnace may shut off.
Cleaning or replacing the flame sensor can resolve this issue.
Limit Switch Tripped: Furnaces have a limit switch that shuts off the furnace if it detects overheating.
This can happen due to restricted airflow, a malfunctioning blower motor, or other issues.
A professional technician can inspect and address these issues.
Gas Supply Issues: Check to ensure that there is a steady supply of natural gas or propane to the furnace.
If there are issues with the gas supply, the furnace may shut off.
Pilot Light or Ignition Problems: If your furnace has a pilot light, ensure that it is lit.
For newer models with electronic ignition, problems with the ignition system can cause the furnace to shut off.
Faulty Blower Motor: A malfunctioning blower motor may prevent the proper circulation of air, leading to overheating and automatic shutdown.
A technician can inspect and repair the blower motor if necessary.
Issues with the Control Board: The control board is a critical component that manages the furnace's operation.
If there are issues with the control board, it can lead to unexpected shutdowns.
Professional diagnosis and replacement may be required.
Pressure Switch Problems: Modern furnaces often have a pressure switch that ensures proper ventilation.
If there are issues with the venting system, the pressure switch may be triggered, causing the furnace to shut off.
Safety Features Activated: Furnaces have safety features that automatically shut down the system in case of overheating, gas leaks, or other potentially dangerous conditions.
Because furnaces involve gas and electrical components, it's crucial to prioritize safety and consult with a qualified HVAC technician for a thorough inspection and proper resolution of the issue.
Regular professional maintenance is also recommended to prevent unexpected shutdowns and ensure the efficient operation of your furnace.

It was a refreshing experience interacting with the Twintech team. From Bob, the sales consultant, who articulated in layman's terms all the options available and reasons for making any selection. This was done without the prevailing pressure tactics so commonplace today.
Before proceeding Mitch, the technician, at our request conducted a service check on our 30 yr old furnace. His report was positive indicating no urgency to replace it. Again no pressure tactics.
Three days after first meeting with Bob, the installation team of Greg and
Spencer completed the installation within the planned time frame.
A very professional, courteous and transparent team which delivered on their promise. I highly recommend Twintech.

I had a really great experience with these guys. The salesman Bob was clearly very knowledgeable about everything to do with heating and cooling a home, spent a lot of time with us going over the details of the job, never rushed us and came back after the install to make sure we were happy. The installation crew was excellent, they covered the floors all the way from outside down to the basement furnace room, kept the place clean, got the work done on time and were very friendly. Ive got 15 years in the contracting/ construction industry and these guys are one of the most professional companys Ive dealt with. Great company!

My old water heater quit on me. I called TwinTech. In less than 4 days, I had my new water heater installed and the old one taken away. The whole process was quick, easy, pleasant, and well done. This is the third time I've dealt with TwinTech and I've been satisfied each time.
